The study of heart rhythms.
A field of study that deals with the relationships of body functions to electrical phenomena (e.g., the effects of electrical stimulation on tissues, the production of electric currents by organs and tissues, and the therapeutic use of electric currents).
The use of electricity to aid the better functioning of the body. Using electrotherapy to relieve pain is said to have arisen in Ancient Rome when a physician put a patient’s painful gouty foot on a live electric eel. At the end of the 19th century when direct electric-current supply was becoming available in people’s homes, a treatment called galvanism became fashionable. It was found that pain could be reduced by attaching electrodes to the skin and applying a direct-current voltage. Later, when an alternating current supply was introduced, a similar treatment followed. The treatment was especially used in sports injuries to reduce inflammation in strains, sprains, sprains, and contusions by improving circulation.
Electroconvulsive therapy (ECT) applying a voltage with surface electrodes on the head across the brain was used extensively in the late 1960s and 1970s to treat depression. At the time there was no theoretical basis to justify it, and recently the treatment has come under considerable criticism because it is believed to have caused permanent brain damage to some patients, especially loss of memory and intelligence.
